Endoscopic ultrasound-guided pancreas biopsy in the hands of a chest physician.

This is the first paper to report sampling of pancreatic lesions by EUS-B-FNA. A 76 year old patient suspected of primary lung cancer presented with a 36 × 24 mm lesion in the pancreas. Thoracentesis showed malignant cells suggestive of mucinous adenocarcinoma, but immunohistochemistry was inconclusive. Due to rapid deterioration of performance status of this frail patient, the program was shortened to EUS-B-FNA of the pancreatic lesion, which showed mucinous adenocarcinoma suggestive of primary pancreatic cancer. We conclude that EUS-B-FNA from a pancreatic lesion in the hands of a chest physician is feasible and diagnostic of a tumor in pancreas.
